Stock Mvmt : From Cust. Consignment at our warehouse to Subcontractor

Hello,

We have a situation with a customer. We have customer consignment in our Warehouse for this customer. We need to send some parts out to Subcontractor. What mvmt can be used for this purpose?

If it was our inventory, we could use mvmt type 541. But this is customer owned so we cannot use the regular 541 mvmt. Can we use 541W mvmt type in Tcode MB1B for this purpose ? If the answer is yes then please advise how I can add this mvmt in the configuration because 541W is not available.

Or if there is any other way of executing this process.

Thanks.
